Trustworthy electronic circuit protectionexpert 25D series www.yint.com.cn Rev:19.3 25D Series 产品简介 压敏电阻的本体是由氧化锌颗粒组成的矩阵结构。颗粒之间的晶 界类似双向 PN结的电气特性，当低电压时，这些晶界处于高阻 抗状态，当电压高时，又会处于击穿状态，是一种非线性器件。。 Product Profile The body of varistor is a matrix structure composed of zinc oxide particles. The grain boundaries between particles are similar to the electrical characteristics of bidirectional PN junctions. When the voltage is low, these grain boundaries are inthe highimpedancestate, and when thevoltage ishigh, they will be in the breakdown state, which is a kind of non-linear device. 应用领域： 通讯基站电源 铁路信号电源 1000V以下低压配电设备、控制设备等等。 楼宇配电 电焊机 Application Communicationbase stationpower supply Railwaysignalpower supply Low voltage distribution equipment, control equipment, etc. below1000V Buildingdistribution Electricwelder 产品料号代码 HOW TO ORDER 产品外形 Product Shape BulkStraight 标准外形 CuttingStraight 切短脚 Out Forming 外弯脚 Y-Forming Y型脚 Cutting Bending 折脚 口 K 的详解 Detailed explanation of 形状类Series D圆片形DiskSeries S方片形Square Series 包装方式 Manner of packing T 编带包装Braidedpacking 压敏电阻Varistor Voltage 最后一位数是 0 的个数 The last digit is thenumber ofzeros. 180=18V 201=200V 182=1800V 瓷片直径或边长 Element Size 压敏电压允许偏差 Varistor voltage allowable deviation K ±10％ L ±15％ D 4 7 1 K T A ll data sheet.com
